Question

我在iOS5之后在iPad上发现了safari中的错误，当子窗口显示警告消息（或确认和之前的启动）时，settimeout在开启窗口上运行停止。当开启窗口再次聚焦时，是否可以继续设置超时？

谢谢！

>>opener page<<

<HEAD> 
<script>
var cnt_t = 0;
var t = function(){ document.getElementById("disp").innerHTML = ++cnt_t; console.log(Math.random());setTimeout(t,1000);};
setTimeout(t,1000);
function openwindow(){
            var path = "settimeout_child.html",param="";
            childWin = window.open(path, "", param);
}
</script>
</HEAD>
<BODY>
<input type="button" value="winopen" onclick = "openwindow()"/>

<div id="disp" style="font-size:100px"></div>
</BODY>



>>child page<<

<HEAD> 
 <script>
var cnt_t = 0;
var t = function(){document.getElementById("disp").innerHTML = ++cnt_t; console.log(Math.random());setTimeout(t,1000);};
setTimeout(t,1000);

</script>
</HEAD>
<BODY>

<input type="button" value="alert" onclick = "javascript:alert(1);"/>
<div id="disp" style="font-size:100px"></div>
</BODY>

在子窗口上显示警告消息后，在opener窗口中的settimeout不起作用
